Most plants depend on microbial partners (symbionts) to help them take up nutrients from the soil. Lu and Hedin set out to identify how these plant-symbiont partnerships contribute to plant distributions and biogeochemical cycles, using an evolution-based modelling approach. The model takes into account…

The three-dimensional structure of plant roots, often referred to as the root system architecture (RSA), is important for soil exploration and nutrient acquisition. The regulation of the RSA is important to prevent overuse of resources and to ensure efficient function. A recent study from Shukla et al.…

Genomics and transcriptomics have brought huge advances in understanding of plant science, but proteomics is both more challenging and in some ways more relevant to understand what is happening inside of a cell. Proteins function largely through their interactions with other proteins, so it is important…

Imaging proteins through fluorescent tagging is tremendously powerful but also tricky. In this very useful paper, Stottard and Rolland survey the properties of 10 fluorescent tags to determine their effectiveness in the low pH environment of the plant cell wall and apoplast. The authors also test the…

Pathogens and pests are bad, but just how bad? And how do different regions of the world compare in terms of crop losses to pathogens and pests? Savary et al. surveyed crop experts from across the globe to address these questions, focusing on five major food crops (wheat, rice, maize, potato and soybean).…

Photosynthesis is one of the most vital and complex processes carried out by plants. During photosynthesis, Photosystem I and II (PSI and PSII) undergo photo-excitation. Excessive photo-excitation can damage and deactivate the PSI by generating reactive oxygen species (ROS). This kind of photoinhibition…

Plants sense and respond to various external stimuli throughout their lifespan. During stress responses brought forth by abiotic or biotic factors, molecular and physiological adjustments mediated by distinct yet interconnected hormone pathways play critical roles in plant survival. Berens et al. investigate…

Cyanobacterial carbon-dioxide concentrating mechanisms elevate intracellular inorganic carbon as bicarbonate, and then concentrate it as carbon-dioxide around the enzyme Rubisco in specialized protein micro-compartments called carboxysomes. The formation of B-carboxysomes involves an aggregation between…
